Core Tip

Core Tip: This study described myeloid sarcoma as the first and only manifestation in an adult patient with mixed lineage leukemia-eleven-nineteen lysine-rich leukemia-positive acute myeloid leukemia. Based on our findings and information from a few previous reports, we speculate that our patient had (1): Transformation of preleukemia cells in the marrow followed by spread to extramedullary sites; or (2) homing of preleukemia cells to extramedullary sites, followed by spreading back to bone marrow. The current study helps increase the awareness of this particular disease and reduce the clinical underdiagnosis rate.
